DEVICE FQR SKEINING HANKS ON THE REEL Filed 001;. 19, 1929 2 Sheets-Sheet 2 Patented Apr. 14, 1931 PATENT oFFlcE FRANZ GOLDBERGER, OF KARLSRUI-IE, GERMANY DEVICE FOR SKEINING HANKS ON THE REEL Application filed October 19, 1929, Serial No. 400,859, and in Germany October 22, 1928.

means it may be mentioned that the thread- 15 holder of substantially plug-like construction is engaged at the inside of the reel by thread detaching and gripping means attached to a short arm or bracket and constructed in such a manner that it will admit so of being pushed into the reel between two hanks. In view thereof the long rod otherwise necessary and which according to the previous art had to be inserted sideways into the reel may be dispensed with. The econis realized by this combination of parts combined with the possibility of being able to dispose the skeining means according to this invention directly on the reeling machine and thereby to avoid the necessity of carrying one of said devices through a distance to the other device, as heretofore generally required, constitutes a very important industrial progress in the skeining art as compared 7 with the previous constructions.

The invention is shown on the accompanying drawing in several embodiments by way of exemplification more or less diagrammatically. In the drawing Fig. 1 is a crosssectional view of the hank. Figs.'2 and 3 illustrate respectively in elevation with parts in section and in plan view the device and its operation according to this invention. Figs.

4t, 5, 6, 7 8 are illustrations of the different positions of the operating parts of the device omy in construction and manipulation which and of the hank operated upon. Figs. 9-18 illustrate a modified form of construction of the device in Fig. 9 in front elevation and in Fig. 10 in side view. Figs. 11, 12, 13, 14, 15, 16, 17 are illustrations of the different stages of operation of this modified construction. Fig. 18 is a longitudinal section ofanother modification to be referred to.

. In Fig. 1 of the drawing the desired skeining or tying ofthe hank is shown diagrammatically with the hank 20 shown in section. The hank is supposed to have been previously subdivided by a kind of comb-like instrumentality into three sections. The skeining thread is indicated at 28. The principle of the invention is more particularly illustrated in Figs. 2 and 3 of the drawing, and in Figs.

4-8 the different stages of movement and positions of the plug-like thread carrier or shuttle are disclosed. It may be assumed that a large number of hanks 20 are disposed in the exemplilication shown on the reel, the said hanks being slightly spaced from each other. In the exemplification represented in the drawing the actuating parts for the thread carrier S, shuttle or the like are shown to be duplicated several times to correspond to the number of hanks of the reel. But it is not absolutely necessary to dispose a plu'- rality'of such devices side by side of each other, inasmuch as allof the interior thread gripping means projecting into the reel may be mounted on a universal beam, while all the exterior thread gripping means are disposed upon an additional universal beam which is likewise common to all the thread gripping means. The last mentioned beam or'rail is preferably guided by means of two special oscillating arms, so that these thread gripping means will perform the same rotary movements as the interior thread gripping means.

The several skeining meansare assumed in the exemplification shown to be disposed on the arm 17 and side by side of each other,

In the direction of the axis a-Z) Fig. 2 the shaft 1 is arranged which is provided at its lower end with an arm 2 carrying at its outer extremity the inner thread gripping means or shuttle S with the sleeve-like spring 4: mounted therein. Motion is imparted to the shaft 1 at its upper end 5. Upon the shaft 1 the sleeve or collar 6 is mounted for axial displacement and is arranged to move along the groove 8 of the shaft 1 which is engaged by the projection 7 on the collar 6 so that the collar will partake in the rotation of the shaft 1. The collar 6 carries at its lower end the arm 9 at the extremity of which the outer thread grippin device or shuttle holder 10 is provided which will therefore in all the positions of the instrumentalities be located exactly opposite the thread gripping means or shuttle holder-S. The arm 9 is provided with a side arm carrying a locking pawl 21 for the thread holder. The latter can be thrown out of engagement by a cam disk operating the pawl or hook 21 at the desired moment. The sleeve 6 is surrounded by the axially displaceable sleeve orcollar 11 which is guided by a projection 12 entering a groove 13 of the sleeve6. To the upper end of the sleeve 11 a relatively fixed arm 15 is secured, so that the simultaneous rotation of the arms 9 and 2 is not interfered with. The entire combina-' tion is rotatably mounted in bearings 16.

The mode of operation of the device is substantially as follows. The arm 2 is disposed between two hanks and is introduced into the reel as indicated in Fig. 3. At the same time the comb 18' which is mounted on the frame 19 subdivides each particular hank in as 7 many sections or skeins, as are to be tied by the 1 thread alon with it. B the rotation ofthe sleeve 11 the arrest) and 2 are simultaneously turned from the position A (Fig. 3) which they had assumed heretofore to the position B, and the thread holder will then have assumed the position according to Fig. 7 Upon now moving the thread holder upwards it'is again inserted into the outer shuttle holding sleeve 10 and is locked in position by the locking pawl 21. In the next stage the thread holder is moved once more into a position above the yarn. By continuing theprocedure described a very superior looping of the skeining thread around thehank is obtained which isequal to thenormal manual-sk'eining opera tion.

In Figs. 918 a modified form of apparatus is shown in which instead of several separate shuttle or thread holders 9, 10 rockingly disposed in guides 16 a continuous bar or rail 35 is employed which is supported at both ends by the arms 36 each of which is adapted to be rocked on an axis c-d-and are moreover disposed to be displaced, or reciprocated in the exemplifieation shown in the direction of the axis cd. By this arrangement substantially the same result is obtained as in the exemplification first mentioned. The rail 35 is displaced by positive means in parallelism of its initial position, so that every point on the rail will describe the same circular arc ABCD as the outer heads of the two rocking arms on which the rail 35 is suspended. The several beams or arms 9 of the exemplificatlon first mentioned Wlll therefore now only constitute 1mag1- nary lines and the heads 10 of the arms are i replaced by the apertures 37 in the rail 35 into which the thread holders S are'adapted to fit. In further pursuance of the principle of this modification the several locking or arresting hooks 21 may be replaced by a um versal locking device in common to all thread 7 holders S, as for instanceby rail 38 disposed within the rail or bar 35 and of smaller thickness than the same. This rail 38 may be longitudinally displaced and, as shown in Fig. 18 may arrest the thread holders by projecting shoulders or the like engaging lateral corresponding'notches of the thread holders and adapted moreover to releasethe holders after a short movement of the rail 38 to the left. If the rail 38 or the projections thereof are made spring-actuated, there is no necessity of providing special regulating means for the re-engagement of the holders S therewith, because the upwardly reduced holders will be free to becomesnappingly engaged and retained in the proper position. For the purpose of releasing the thread holders S however the bar or rail 38 must be controlled by positive means which may for instance be effected by a grooved drum or by means of a cam 39 which are operated in the well known manner and in accordance with the requirements of the particular case. i

The utilization ofythe bar or rail 35 to replace the several upper thread carrying means 9 and of the guiding sleeves 16therefor will entail a correspondingarrangement of the lower thread carryingmeans 2 which may bemounted in a continuous bar or rail 10 the central planeof which will have to coincide withjthe rotatingaxes 'c-d of the two rocking arms=36 and adaptedto be displaced in this plane, provided the heads '3 of the lower thread gripping means 2 arcintended to describethe same circular arcs as the apertures 37. The movement should of course be such that the length c'of the alignlarly projecting lower arms 2 should be the same as that of the rocking arms 36.

and the centres of which are arranged in an extension of an imaginary axis of the bores 37. In Figs. 12 to 17 the most important parts of the movements executed by the thread holders S are shown in successive steps similar to the representation otFigures 4 to 8 of the drawing.

The essential feature of the new skeining device is the fact that the thread gripping means or the like is adapted to move in a circular path around an existing or imaginary axis intermittingly first in one and then in the other direction, and that during the interruptions of the movement the change of position of a thread holder or shuttle takes place in the downward and respectively in the upward direction in the desired manner of succession, the said thread holder carrying the skeining thread along with it.

While I have described for the purpose of disclosure of my invention in some details some specific embodiments of the principles of my invention, it will be apparent thatnumerous other modifications and changes may be made, and I, therefore, do not desire to be limited in the broader aspects of my invention to the specific construction described and illustrated, except as otherwise appears from the appended claims.
